The dark side is cool for those who want a car tire...I am looking more for a fat tire (bike tire) that will give the fat boy look. What is the maximum size fat tire I can use on my stock rim without having to change any other parts?Sorry for the ignorance on my part, just not too familiar with the tires. GOALS: I am looking to customize my VTX1300C may even go into chopper mode with the fat boy look. Just want to start off slow. please educate me..Joe cool..
